As described here, Cobot offers four different ways to check-in your members. This free add-on is one easy way to manage this. Head over to Add-ons » Available Add-ons » Members checked in » Install to activate it. It will then appear under the 'Manage' tab in your menu.
The add on shows you:
Member name & plan name
Time pass with which the member is checked in under (if applicable)
Check-in time
Check-in and check-out button
The check-in and check-out time for members on plans without Time Passes will default to the duration of their pass settings.
For example, if your members has a one hour pass, the default check-out time will be one hour past the time you check them in. See the screenshot above.
If the member does not have time passes on their plan, then the default check-out time is 3:59 am. This will only be applied to the member's check-out time if you did not manually click on 'Check out'. If you do, then that will be the time that is posted.
